The Best of Both Worlds
In the quest for sustainable manufacturing, engineers often face a dilemma: choose the thermal efficiency of a Regenerative Thermal Oxidizer (RTO) or the low operating temperature of a Catalytic Oxidizer.
The solution lies in the hybrid technology sought by many as a catalytic oxidizer regenerative system—technically known as the Regenerative Catalytic Oxidizer (RCO). At Cadair.net, we engineer these advanced systems to deliver the highest possible ROI for your Control of Gaseous emissions.
1. How a “Catalytic Oxidizer Regenerative” System Works
An RCO is essentially an RTO with a layer of industrial catalyst added to the ceramic heat exchange beds. This combination creates a powerful synergy for Waste gas treatment equipment:
- Regenerative Heat Recovery: Like an RTO, it uses ceramic media to capture up to 95% of the heat from the exhaust.
- Catalytic Reaction: The catalyst layer allows the VOC destruction to happen at just 300°C–400°C, rather than the 800°C required by thermal oxidation.
This means the system requires significantly less energy to maintain its operating temperature, often running on zero fuel once the process is started.
2. RCO vs. Standard RTO: Energy Savings
Why upgrade from a standard thermal unit to a catalytic oxidizer regenerative design? The answer is fuel cost.
- Standard RTO: Must heat air to ~800°C. Even with heat recovery, fuel is needed if VOC concentration is low.
- RCO System: Only heats air to ~350°C. The temperature gap (Delta T) is much smaller, meaning your gas burner barely needs to fire.
For facilities with stable, low-concentration emissions (like printing or coating), an RCO is the undisputed champion of operating costs.

3. Is Your Process Suitable for RCO?
While a catalytic oxidizer regenerative system is efficient, it is not for everyone. The catalyst is sensitive.
- Ideal for: Clean VOC streams (alcohols, ketones, esters) found in printing, packaging, and lithium battery manufacturing.
- Avoid if: Your exhaust contains “catalyst poisons” such as sulfur, silicones, heavy metals, or high levels of particulates. In these cases, a robust RTO is the safer choice.
